DNA Loading buffer I

The GenLadder 50bp (ready-to-use) is an ideal DNA size marker for fragment sizes from 50 - 1500bp. The bands at 200bp, 500bp and 1200bp bands light up more intensive for better orientation. Each band has been calibrated with respect to base pair size. Thus, an accurate determination of product size is possible. No ambiguous bands are visible. Band sizes: 50 (ca. 30ng/5µL), 100 (ca. 27ng/5µL), 150 (ca. 30ng/5µL), 200 (2x) (ca. 67ng/5µL), 250 (ca. 25ng/5µL), 300 (ca. 20ng/5µL), 350 (ca. 18ng/5µL), 400 (ca. 27ng/5µL), 450 (ca. 23ng/5µL), 500 (2x) (ca. 67ng/5µL), 600 (ca. 20ng/5µL), 700 (ca. 23ng/5µL), 800 (ca. 27ng/5µL), 900 (ca. 30ng/5µL), 1000 (ca. 33ng/5µL), 1200 (2X) (ca. 70ng/5µL) and 1500bp (ca. 40ng/5µL). GenLadder 50bp is already dissolved in loading buffer with tracking dye (Orange G) that does not overlab with bands in the range between 500bp and and smaller. GenLadder DNA ladders are available in a ready-to-use format (premixed with 6X DNA Loading Dye): M3094 (GenLadder 1kbp extended up to 25 kbp ready-to-use) > and M3328 (GenLadder 1kbp ready-to-use) > or our ready-to-use premix M3072 (GenLadder 50bp) > with 6X Orange DNA Loading Dye. The DNA Gel Loading Dyes can also be ordered separately: M3308 (DNA Gel Loading Dye with Bromophenol and Xylene Cyanol FF) >, M3321 (DNA Gel Loading Dye with Orange G) >.

With the synthetic GenLadder XLarge, even larger plasmid insertions and vector plasmids can be determined clearly and precisely in size by gel electrophoresis in the range of 250 - 25000 base pairs after restriction digests. The Genaxxon GenLadder XLarge shows 14 bands. The approximate mass of the DNA in each band is given for a 5µL load (0.52µg/lane). Additionally the 1000 bp and 3000 bp are intensified for better and faster orientation in 1.0 - 1.5% agarose gels. Please avoid repeated freez-thaw cycles. We recommend to portion the product into smaller aliquots. Source: PCR products and double-stranded DNA digested with appropriate restriction enzymes, are phenol extracted and equilibrated to 10mM Tris-HCl (pH8.0) and 10mM EDTA. GenLadder DNA ladders are available in a ready-to-use format (premixed with 6X DNA Loading Dye): M3094 (GenLadder 1kbp extended up to 25 kbp ready-to-use) > and M3328 (GenLadder 1kbp ready-to-use) > or our ready-to-use premix M3072 (GenLadder 50bp) > with 6X Orange DNA Loading Dye. The DNA Gel Loading Dyes can also be ordered separately: M3308 (DNA Gel Loading Dye with Bromophenol and Xylene Cyanol FF) >, M3321 (DNA Gel Loading Dye with Orange G) >.

Our DNA marker GenLadder 100 bp Plus with loading dye is an ideal tool to determine the size of double stranded DNA in the range of 100 - 3000 bp. The additional bands at 1.5kbp and 3.0kbp allow to assign additional DNA fragment sizes in the range up to 3000 bp without using an additional 1kbp DNA marker. The Gene Ladder 100 bp Plus consists of 12 fragments in sizes between 100 - 1000bp spaced 100bp apart. In addition, there are further bands at 1500bp and 3000bp. The 500bp and 1500bp fragment show stronger intensity to allow easier identification. All fragments are 'blunt-ended'. The GenLadder can be directly labeled at the 5'-end with radioisotopes using T4 polynucleotide Kinase for visualisation by autoradiography. Fragment sizes (in base pairs): 3000 bp (40ng/5µL), 2x 1500 bp (70ng/5µL), 1000 bp (50ng/5µL), 900 bp (40ng/5µL), 800 bp (40ng/5µL), 700 bp (30ng/5µL), 600 bp (30ng/5µL), 2x 500 bp (90ng/5µL), 400 bp (40ng/5µL), 300 bp (30ng/5µL), 200 bp (40ng/5µL), 100 bp (40ng/5µL). The DNA marker is already dissolved in buffer containing orange G and Xylene cyanol FF as tracking dyes. The total concentration of the DNA-Marker is 0.1µg/µL (108µg/mL). The recommended amount of DNA marker per lane is 0,5μg (5µL). GenLadder DNA ladders are available in a ready-to-use format (premixed with 6X DNA Loading Dye): M3094 (GenLadder 1kbp extended up to 25 kbp ready-to-use) > and M3328 (GenLadder 1kbp ready-to-use) > or our ready-to-use premix M3072 (GenLadder 50bp) > with 6X Orange DNA Loading Dye.
